A contract
generally consists of an offer, acceptance, and consideration. In business, the
offer typically consists of a purchase order, and the acceptance is the
shipping of the goods or the providing of services named in the purchase order.
The consideration is the purchase price. Offer, acceptance, and consideration
can be implied depending on the circumstances.
With some important exceptions (such as sales
of real property), contracts do not have to be in writing. Although the UCC
provides that all contracts over $1,000 should be in writing, UCC 2-201(1), MCL 440.2201(1),
there is a notable exception to this rule. Where a seller of goods ships to a
buyer and the buyer receives and retains those goods, there is an implication
that a contract exists. If the buyer fails to timely return the goods, no
writing is needed to imply that the buyer intended to contract for the purchase
price of the goods. UCC 2-201(3)(c), MCL 440.2201(3)(c).
The UCC also provides for substitutes for a writing or exceptions to the
writing requirement where there is a written confirmation between merchants,
UCC 2-201(2), MCL 440.2201(2);
specially manufactured goods, UCC 2-201(3)(a), MCL 440.2201(3)(a);
an agreement admitted in court, UCC 2-201(3)(b), MCL 440.2201(3)(b);
and partially performed agreements, UCC 2-201(3)(c), MCL 440.2201(3)(c).
The UCC does not require price terms,
delivery terms, or other details for the sale of goods. Past experience of the
parties and other statutory default provisions will help to determine most of
the terms of a contract, including a purchase price. Therefore, it is fairly
easy under the UCC to establish the existence of a contract without having to
prove specifically the elements of offer, acceptance, and consideration.
The contract has to be entered into before
the goods are delivered or services are provided. For that reason, the purchase
order and the documentation before the sale, including the credit application,
become the contract between the parties. The credit application is an often
overlooked but important document. Credit applications often set forth extremely
important terms such as interest rates to be paid should the account become
delinquent, personal guaranties to be invoked if the account becomes
delinquent, the parties’ agreement concerning full settlement checks, etc. For
a sample credit application, see .
A common misconception among business people
is that an invoice is a contract. An invoice may contain a description of the
goods, shipping dates, and price terms, but it is not a contract. The invoice
is prepared and mailed out after the goods are shipped and after the contract
is entered into. For this reason, the terms printed on the back of invoices
(most companies insist on filling up the back of their invoices with various
terms in small print: immediate inspection, immediate return of any defective
goods, a return authorization number on any defective goods, and so forth) are
generally not enforceable. See Power Press Sales Co v MSI Battle Creek
Stamping, 238 Mich App 173,
183, 604 NW2d 772 (1999). Thus, for example, if a customer voluntarily agrees
to pay interest on a delinquent account based on the terms set forth in the
invoice, that is all well and good, but if the customer later decides not to
pay the interest, it is likely that a court will not enforce the interest terms
if they are only in the invoice.
The courts will generally enforce contracts
that are within the parties’ expectations. If there is a one-sided (unilateral)
mistake, the contract is enforceable. However, if there is a mutual mistake,
the court will generally not enforce it. For example, if both parties thought
that the steel was Grade A worth $57.00 per pound and it turned out, by mistake
of both parties, that the steel was Grade B, then the court will not enforce
the contract.
Sometimes contracts are purely unilateral. In
other words, acceptance of the contract occurs through performance. For
example, if someone offers to pay $500 if the contracting party drives a car to
California, acceptance occurs when the car is driven to California.
Consideration is difficult to measure and
courts often will not bother to measure it at all. If there is the existence of
any legal consideration, the contract will most likely be enforced. Thus, if
the buyer overpays for a product, a court will not question the overpayment
unless there was actual fraud or a mutual mistake.
